Ariana Grande lands on the cover of InStyle for its December issue, looking amazing in a strapless red dress. The "Break Free" singer sports a gorgeous Prabal Gurung Resort 2015 dress, a pair of diamond and 18-karat gold stud earrings by Jennifer Meyer and her signature high ponytail hair on the front page.

In an interview for the spread, Grande once again dispels rumors that she acted like a diva and once was supposedly heard wishing her fans to "f**king die." To the magazine, Grande says, "That one had me laughing hysterically. Because anyone who knows me or has done any homework at all knows that I would literally give a limb for my fans."

With her success in music, comes all the attention. "Some things are easier now, and others are harder. I never expected to be in a position where so many people are invested in every little thing I say and so," she says of fame and personal life. When she learns of some rumors about her, "part of me wants to say, 'Oh my god, that's so not me! Please don't believe that!' "

Grande also calls rumor of her being difficult to work with is "fictional." "I take my work seriously, but I don't take myself too seriously. I think that's the biggest misconception about me," the 21-year-old star says.
